Johnny Cash’s step-daughter, Rosey Nix Adams and her fiddle player Jimmy Campbell were found dead on their tour bus in Clarksville, Tennessee from Carbon monoxide poisoning. Heaters that had been left on in the converted school bus were blamed for the accident. Campbell was also a regular member of Nashville band, The Sidemen and performed with bluegrass great Bill Monroe and Jim and Jesse.
